Abstract

L'invention concerne une roue libre à corps de blocage (1) ainsi qu'une cage (4, 14) associée. La roue libre à corps de blocage (1) présente une bague intérieure (2), une bague extérieure (3) disposée coaxialement par rapport à celle-ci, une cage à corps de blocage (4, 14), disposée dans une fente entre la bague intérieure (2) et la bague extérieure (3), et une pluralité de corps de blocage (5), qui forment, dans une position de blocage, une liaison par friction avec la bague intérieure (2) et la bague extérieure (3) et qui permettent, dans une position de roue libre, un mouvement de rotation de la bague intérieure (2) par rapport à la bague extérieure (3). La cage à corps de blocage (4, 14) présente le long de sa périphérie, des entretoises réparties de manière équidistante, axiales (6, 16) ainsi que des poches, dans chacune desquelles est logé un des corps de blocage (5). Les entretoises (6, 16) présentent une élasticité supérieure à celle des corps de blocage (5). Les entretoises (6, 16) présentent une surface faisant ressort (7) qui est mise en contact, uniquement dans la position de roue libre, avec le corps de blocage (5) adjacent.
